I spent some time adjusting the tank-to-leading edge joints tonight. The tanks had some “pillowing” where it attaches to the leading edge, due to the tanks being a tiny bit larger than the leading edges. This seems to be a common problem amongst RV builders.
I fabricated 4 shims in total, and installed them between the leading edge ribs and tank attach strips to get the leading edge skins to line up with the tank skins. It’s not perfect, but it looks a lot better.
